Hey! Pretty stranger :D

AsnwEr:

  • Number of boys in class = 12

To find:

  • Number of girls in class?

Solution:

Given that,

  • The ratio of no. of boys to no. of girls in a class is 4:5.

Therefore,

→ 12/x = 4/5

→ x = 12 × 5/4

→ x = 60/4

→ x = 15

∴ Hence, number of girls in a class is 15.
